There are three types of fiber optic distribution frames on the market: one is the 110 hit line distribution frame (i.e., modular distribution frame), the second is a straight-through distribution frame (card-connected distribution frame), and the third is an electronic distribution frame.
1, 110 playing line type distribution frame
The front panel of 110 wiring distribution frame is RJ45 interface, each interface has a digital logo, 110 wiring distribution frame is on the rear panel of the wiring module, which is marked with T568A and T568B wiring standard, according to the actual demand in accordance with the wiring sequence to play the network cable.
2、Through-type distribution frame
Straight-through distribution frame front and rear panels are RJ45 interfaces, each interface on the panel has a digital logo, the current market is common 24-port and 48-port two sizes of the distribution frame. In fact, the straight-through type distribution frame is more convenient to use than 110 wire distribution frame, directly into the network cable can be used, more suitable for high-density wiring needs.
3, electronic distribution frame
The use of electronic distribution frame and straight-through distribution frame, directly into the network cable can be. Electronic distribution frame can analyze the formation of data through the probe line, for network maintenance personnel to bring convenience, which detects the form of port and link two kinds of probing methods, different forms of the use of the cable is not the same, according to the equipment can be determined. Due to the relatively high cost of electronic distribution frame, the current project is used less.
